Hello,
I have a detached log cabin at the end of the garden to become a DIY workshop, with main tool being a DIY CNC, along with most tyical power tools you can think off (circ. saw, mitre saw, planar etc). I want to future proof it for when I can afford other higher amperage tools like a table saw, extraction, thicknesser etc.
I'm intending to buy and partially fit most sockets and cabling, then let a qualified electrician complete all the connections and certify it.
House CU to workshop is ~30 meters. Going to get a 50 meter, 3-core 10 mm^2 SWA PVC cable to run this distance underground (voltage drop should be within tolerance).
Should cat5e cable also be SWA PVC if ran in the trench? I know you can get the two combined, but it's so expensive.
Do these cables need to be in any truncing underground? I know I need to put warning tape above it before filling back the trench.
What size MCB do I connect it to on my house's CU? Does it also need to be on a RCD?
Does the workshop CU need to have an RCD? Both, workshop only or house only?
Workshop should be metal clad CU? Can I earth it to the house or is 30-40 meter 10 mm^2 too long of a run? Alternative is eath bar?
I'm thinking of having 4 MCB:
One for just the CNC. Size MCB?
One for sockets. Size MCB? (maybe 10 2-gang sockets). or should I give some sockets to the CNC's MCB (it's power draw shouldn't be that high tbh)?
One for lighting. 8 LED panels. 2 outdoor wall mounted lights. 2 outdoor security/motion lights.
One MCB/space as spare.
Radial or ring? (radial seems more logical, as I won't have sockets on all 4 walls).
What size and what type cables should I run in to the sockets and to the lighting, is it 3 Core and Earth PVC H6243Y Cable?
1.5 mm for lights?
2.5 mm for sockets that will run power tools?
2.5 mm to the CNC?
One 2-gang outdoor socket will be on the external wall, should this have a seporate in-line fuse/spur?
Edit: I've already met and have a registered electrician to do the final connection and anything I'm unsure of.
Kind Regards!
